What is Propertied

Propertied is a tiny Clojure library that deals with Java property lists.

Project Maturity

Propertied is not a young project and unlikely to radically change (it is too small in scope).

Artifacts

Propertied artifacts are released to Clojars. If you are using Maven, add the following repository definition to your pom.xml:

<repository>
  <id>clojars.org</id>
  <url>http://clojars.org/repo</url>
</repository>

The Most Recent Release

With Leiningen:

[clojurewerkz/propertied "1.2.0"]

With Maven:

<dependency>
  <groupId>clojurewerkz</groupId>
  <artifactId>propertied</artifactId>
  <version>1.2.0</version>
</dependency>

Documentation & Examples

Propertied makes it easy to convert property lists (java.util.Properties) into Clojure maps and vice versa. Thus working with property lists is generally as straightforward as working with maps.

clojurewerkz.propertied.properties/load-from is a polymorphic function that instantiates a property list from an input (e.g. a map or property file).

clojurewerkz.propertied.properties/store-to takes a map and stores it into a .properties file (an output stream or anything else that can be coerced to java.io.Writer).

clojurewerkz.propertied.properties/properties->map is a function that converts a java.util.Properties to an immutable map. clojurewerkz.propertied.properties/map->properties converts the opposite way.

(require '[clojurewerkz.propertied.properties :as p])

(p/load-from {"a key" "a value"})
;= {"a key" "a value"}
(class (p/load-from {"a key" "a value"}))
;= java.util.Properties
(let [pl (p/load-from {"a key" "a value"})]
  (p/properties->map pl))
;= {"a key" "a value"}

;; converting keys to keywords
(let [pl (p/load-from {"key" "value"})]
  (p/properties->map p true))
;= {:key "a value"}

;; loading from files and InputStreams
(require '[clojure.java.io :as io])

(p/load-from (io/resource "resource/on/classpath.properties"))
(p/load-from (io/file "resource/on/classpath.properties"))

;; storing to property files (.properties)
(p/store-to {"name" "Michael" "age" "28"} "/tmp/michael.properties")
(p/store-to {"name" "Michael" "age" "28"} (io/file "/tmp/michael.properties"))
(p/store-to {"name" "Michael" "age" "28"} (java.io.File/createTempFile "michael" ".properties"))
